Provide exceptional customer service by offering clients access to technology powered by Guidewire. Guidewire was identified as a leader in the January 2016 Gartner “Magic Quadrant for P&C Insurance Policy Management Modules, North America[1]”;

Bring new products and product enhancements to market more quickly;

These products will replace the company’s internally-developed policy administration and billing management systems. With these selections, Seibels will be able to expand its BPO offering to provide the benefits of Guidewire InsuranceSuite™ to its customers.

Seibels selected Guidewire DataHub™ and InfoCenter as its new data warehouse and business intelligence solutions, and Guidewire Gateway Portal for Agents™ to provide agents with more self-service functionality and greater collaboration capabilities.
